Able to play mists decently? (bootcamping and other things)

Hey there, have been digging through the internet left and right but have decided to just ask my questions here.
I'm thinking of returning to WOW after a year and half or so break to play casually, see the new content, try some stuff, basically I've been getting the itch to play badly since mists came out. Didn't really like cataclysm.
Is my computer even at a level for it to be worth returning? I'm aware the card is outdated and such, but would I be able to see decent-good performance all-round if I used bootcamp (which I have no idea how to do/have never used)?
